Banners at the school store were on sale for $3 off the rugular price. Louis brought 4 banners on sale and paid a total of $18.
Naddik [55]

Answer:

$7.50

Step-by-step explanation:

4 x 3.00 = $12.00  3.00 off the regular price makes it 12.00 for all the banners

12.00 + 18.00 = 30.00   you add the sale price with the 12.00 to get the total of each banner before the store gave the sale price.

30.00 divide by 4 = 7.50   to find out what the regular price of the banner you divide by the total of banners you bought to get the price of each banner before the sale.

Researchers have discovered a new genetic marker for a form of cancer. Twelve percent of the overall population carry this marke
In-s [12.5K]

Answer:

The probability that a person with the marker develops cancer is 0.0725.

Step-by-step explanation:

Let's denote the events as follows:

<em>A</em> = a person has cancer

<em>B</em> = a person carries the marker.

<u>Given:</u>

P (A) = 0.03

P (B) = 0.12

P (B|A) = 0.29

The conditional probability of an event <em>X</em> provided that another event <em>Y</em> has already occurred is:

P(X|Y)=\frac{P(Y|X)P(X)}{P(Y)}

Use the conditional probability formula to compute the probability that a person with the marker develops cancer.

P(A|B)=\frac{P(B|A)P(A)}{P(B)} =\frac{0.29\times0.03}{0.12}=0.0725

Thus, the probability that a person with the marker develops cancer is 0.0725.
